Jailbreak Your iPhone on a PC

This is a guide that will teach you how to jailbreak your iPod Touch, iPhone, or iPad on a PC only if you are running firmwares 3.1.2 or 3.1.3. Once you have jailbroken your iPhone you will have the application called Cydia that lets you install other applications onto it. Although before you can jailbreak your iPod you need to find out what firmware version you have.

To follow these instructions you must be using an activated device not stuck on the Connect to iTunes or Emergency Call screen.

To find the firmware version of your iPhone:

       1) Turn on your iPhone and click on the application called settings.
       2) Go to the section called general. It should be the third from the top.
       3) Now go to the section called about. It should be the first on the list.
       4) Scroll down untill you find where it says firmware version.

Congratulations now that you have found out the firmware version expand the section of this guide that applys to you and your iPhone.

Firmware 3.1.2 and 3.1.3 using Spirit

First here is a brief explanation of spirit from the official website http://www.spiritjb.com.

__________________________________________________________________

What's Spirit?

  • Spirit is an untethered jailbreak for iPad, iPhone, and iPod touch on the latest firmwares.

  • Spirit is not a carrier unlock.

  • If you currently are using a tethered jailbreak, you have to restore to use Spirit. Do not upgrade if you use an unlock on an iPhone 3G or 3GS. (You can, however, restore to 3.1.2 if you have SHSH blobs for that version.)

__________________________________________________________________

       NOTE: Any version of iTunes 9 until version 9.1.1 will work.

1) Download the Spirit Jailbreak from here and save it to your desktop.
2) Double click the Spirit application on your desktop to launch it.

      

NOTE: If you have Windows 7 you may need to run Spirit in compatibility mode for Windows 98. Before launching right click Spirit.exe and select Properties from the contextual menu. Then from the Compatibility tab select Windows 98 from the Compatibility Mode dropdown. Click Apply then Ok

3) Connect your iPhone and press the Jailbreak button.
4) The Spirit app will then let you know the jailbreak is complete.
5) Your iPhone will reboot and show you a progress indicator. Once this finishes your iPhone will be jailbroken with Cydia installed!
